10 @ZZ w/wm it may concern,.-

Be it known that I, CHARLES CLAYTON, a citizen of the United States, residing at Dayton, in the county of Montgomery' and State of Ohio, have invented certain new and useful Improvements in Concrete-Block Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part lof this specification.

This invention relates to new and useful improvements in machines for making concrete building-blocks, and possesses the new and useful features hereinafter described and claimed.

Preceding a detail description of the invention reference is made to the accompanying` drawings, of which- Figure I is a top plan view of the machine. Fig. II is a front elevation of the machine. Fig. III is an end elevation. Fig. IV is a cross-section. Fig. V is a longitudinal section with the upper portion of the machine removed.

The invention has for its object to provide a machine of the above type in which the molded bricks or blocks of concrete are removed from the machine in a convenient manner and without coming in contact di rectly with the blocks. In other words, the removal of the molded blocks is accomplished without direct handling.

Other features of importance may be referred to-for example, the construction and assembling of the mold and the mounting and manipulation of the core-pins by means of which the transverse openings in the blocks are obtained.

In a detail description of the invention similar reference characters indicate corresponding parts.

The base or the main supporting-frame 1 of the machine is constructed of suitable uprights and cross-pieces 1, which are braced by suitable corner-pieces 1, the whole providing a substantial framework upon which are mounted longitudinally two angle-irons or channel-bars 2 2. Journaled in these angleirons 2 2 are a series of rollers et, over which passes an endless cable or rope 5, which passes around larger end rollers 6 6, which are journaled in bearings 6 at each end of the cable.

machine. The portion of the rollers 6 over which said cable passes consists of a grooved wheel 6, which receives said rope. Above and free from the rope or cable is a carriage consisting of rails 7 7, which rest upon therollers 4 4 and support the mold-box or flask consisting of the follow-board 8, the side walls 12 12, and the end walls 1515.

The parts of the flask or mold-box just enumerated are supported in a frame consisting of angle-irons 18, joined at their bottom ends by the channel-bars 2 2 and at their upper ends by angle-bars 26. The end wall 15 of said mold-box has a dovetailconnection with a supporting-wall 10, which is supported upon a horizontal push-board 8 by a brace 1 1. The push-board 8 is in alinement with the follow-board S and imparts movement thereto. rIhe said push-board 8 is also supported upon the carriage 7 similar to the follow-board 8. The side walls 12 12 are removable, as are also the end walls 15 and 15. The latter end wall is maintained in position on the inside of a door 9 and abuts with thc ends of the side walls 12 12. This door 9 has suitable hinges and is secured by means of a spring-latch 9. The inner sides of the side plates or walls 12 12 are provided with core-bars 13, semicircular in cross-section, and the end plates or walls 15 15 are likewise provided with such bars or cores. These parts form grooves in the 'corresponding sides of the block and provide suitable recesses which are utilized in constructing a wall of the blocks.

14 designates transverse core-pins-which are projected through the mold transversely and provide spaces extending entirely through the block vertically. These core-pins are withdrawn from the molded form or block by attaching them to crank-arms 16, which are fixed to a rod 16, mounted on the bed or framework of the machine and operated through a lever 17 to withdraw the .core-pins from the block. The rope or cable 5 is attached to the push or pull floor S at the point S, and the rope or cable passes freely below the follow-board 8. Said follow-board, it will be observed, abuts with the ends of the push or pull board S. the side walls of the mold or flask are not movable in either direction from the rope or The face of the block may be formed on the bottom or on the top. In case it is desired to form the face on the bottom the flatsurface follow-board 8 is removed and a face- TOO IOS

plate isV placed on" the carria'ge'7 inthe place thereof, and the said follow-board 8 is used as a tamping-plate on top.

As shown in the drawings, the machine is equipped for forming the face of the block on top. The face-plate frame 24, having handles 26, by which it is elevated and lowered in a guide-frame 27, which is mounted above the mold. The face-plates 25 may be of any suitable surface design and are detachable from the supporting-frame by means of a dovetail connection 25 between the two parts. The guideframe, consisting of the parts 27, is joined by a yoke 23 at the top. After the operation of tamping the surface of the block the faceplate 25 may be held in an elevated position by means of a catch 28 on the top cross-piece of the frame, which engages in a loop 29 on the top of the face-plate support 24. The guides 27 are supported by upright frames 23. The finished blocks areremoved from the end of the mold, which is closed by the In this operation the door is opened and the follow-board supporting the finished block and the two end walls 15 15 is moved to the right, as shown in either Fig. 3 or 5, and the molded block is entirely removed from between the side plates of the mold, which during such movement remain stationary. The carriage supporting the follow-board 8 and the push-board 8 is moved through the cable or rope 5 from the crank 29 which is operated from one end of the machine, said crank being on the roller 6 at that end of the machine. The upper frame consisting of the parts 27, 23, and 23 is mounted on a frame consisting of end pieces 26 and side pieces 20, which constitute a frame hinged at 19 and held closed by a spring-catch 21. rIhis superstructure is only employed when the face is formed on the upper side of the block and is dispensed with when the face is formed on the lower side of the block.v In the latter case the follow-board 8 is placed upon the upper side of the block and is tamped through the requisite pressure being applied thereto.

Having described my invention, I claim- 1. In a' concrete-block machine, a carriage, a series of rollers supporting said carriage, a follow-board supportedv on said carriage a mold-box supported upon said followboard, a push-board engaging an end of the follow-board, and a rope or cable having a connection with the push-board, said rope or cable passing freely below the followboard, and means for rotating said cable to impart movement to the follow-board from the push-board to deliver the molded block from the mold, substantially'as described.

2. In a concrete-block machine, a carriage, a series of rollers supporting said car- 25 is supported upon a riage, a follow-board on said carriage, a mold or flask supported on said follow-board, a

door inclosing one cf the end plates of said flask or mold, a push-board supporting the other end plate of said mold, said push-board engaging an end of the follow-board to move the same, a cable or rope passing over the rollers and having a connection with said push-board, end rollers over which said rope or cable passes, and means for rotating said rope or cable to impart movement to the follow-board through the push-board to remove the finished block from the mold.
